Title: User-controlled reception restriction in a radio communication unit
Inventor: NAKADA SHINNICHI
IPC: H04W88/02
Filed: 2000-03-22
Abstract: User-controlled restriction of service reception, for example in a protected area such as a plane or a hospital is achieved by allowing the user to set a threshold for a received signal strength below which reception is disabled. Thus the threshold can be set high in a protected area. Additionally, a predetermined threshold operates so that reception is disabled when the communication unit is outside the range of a base station so as to reduce power consumption by the unit. The unit comprises a radio transceiver 1, a programmer 3, and a display 5. the programmer causes the prevailing received signal level to be displayed and stores the user input threshold and the predetermined threshold and sets the transceiver unit 1 into a transmission mode, a reception mode, a waiting mode, or an out-of range mode in accordance with th comparison of the received signal level with the thresholds.

Title: A rake receiver and a method of operating a rake receiver
Inventor: GIANCOLA DIEGO
IPC: H04B1/707
Filed: 2000-05-16
Abstract: A rake receiver 40 includes, in a finger, a subtractor 31 which is arranged to detect the difference in power between early and late samples E1P, L1P of a signal being received at a particular position in the code space. A subtractor 33 operates in the same way on an adjacent finger. The receiver includes multipliers 32, 34 which operate to reduce the amplitude of signals provided to the subtractors 31, 33 if it is detected that the fingers are close together in the code space. The fingers are thereby opposed from moving together and the signals from the fingers thereby continue to be processed separately. Data for controlling the multiplication factor of the multipliers 32, 34 is stored in a look-up table 41. The receiver may be used in a radio receiver or radio telephone.

IPC: H01M8/06
Filed: 2000-10-05
Abstract: A method of operating a fuel cell having an anode passage. The method includes collecting hydrogen from the anode passage (16) that does not pass through the catalyst membrane. The hydrogen, together with water and inert gases, are directed to a hydrogen storage container (30). The hydrogen storage container includes a hydrogen storage media such as metal hydride, carbon adsorbents, or carbon nanofibres. A sensor determines whether or not the vehicle is moving. When the vehicle is stopped or moving slowly, the surplus hydrogen is directed to the hydrogen storage container (30) for temporary storage. When the sensor determines that the vehicle is moving at a high speed, the surplus hydrogen is vented to atmosphere and the hydrogen storage media is renewed. Electrically controlled valves (34) direct the purged hydrogen and renew the hydrogen storage media. The valves (34) are controlled by an electronic controller (24) that monitors vehicle speed and hydrogen build-up within the storage media.

Title: Multi-hop packet data routing system
Inventor: MAYES KEITH EDWARD
IPC: H04L12/701
Filed: 2000-10-19
Abstract: Packet data is routed from a source node to a destination node through a plurality of intermediate nodes, hopping from node to node. The nodes may be any suitable transceiver such as cellular telephone handsets. Hopping the data between nodes minimises the transmission power required and reduces the possibility of interference compared with transmitting data between source and destination addresses in a single transmission. In order to monitor signal quality or aid in recovery processes, all calls must be routed through a central point or mobile switching centre. In a multi point transmission network, data may not be able to be routed through the MSC. A Special node is introduced into the network which can distort the flow of traffic in the network so that data transmissions pass through the special node. The special node may achieve this by producing artificial information relating to the cost or power loss involved in data hops between nodes to ensure that the lowest cost route is through itself.

Title: Ciphering keys used in handover between different cellular communication networks
Inventor: BARRETT STEPHEN JOHN
IPC: H04W36/14
Filed: 2001-07-14
Abstract: A handover method comprising encrypting communication between a first network node 6 of a first (old) network 2 and a communication unit (mobile station) 22 using a first ciphering key, encrypting communication between a second network node 14 of a second (new) network 4 and a communication unit using a second ciphering key, wherein the handover is performed without the second network retrieving the second cipher key or information relating to the second cipher key. This results in a reduction of handover delay. The second cipher key may be passed from the first network to the second network as part of a handover message. The method may further comprise encrypting communication between the communication unit and a network node using a third ciphering key during the handover process. The third cipher key may be used to encrypt communication in addition to the first and second cipher keys used to encrypt communication in the first and second networks respectively. Alternatively the third cipher key may only be used to encrypt communication during the handover process. In a further embodiment communication may be unencrypted during the handover process.

Title: Parallel convolutional encoder and method of operation
Inventor: MACDOUGALL SCOTT
IPC: H03M13/23
Filed: 2001-09-28
Abstract: A method of convolutionally encoding (700) a data stream includes inputting a first block of two or more bits (710) in parallel into a shift register. A number of intermediate calculations (715) are performed in parallel using a number of respective delayed shift register outputs; and said number of intermediate calculations (715) are output (725) to form a convolutionally encoded sequence. A convolutional encoder, communication unit and communication system adapted to implement the convolutional encoder are also described. Setting up a register (of individual bits stored in words), which is longer than the constraint length means that a relatively large number of input bits can be read from memory only once, thus avoiding many independent moves of operands to and from memory. Since the register is longer than the constraint length, the register need only be shifted once for every 'a+1' input bits, rather than once for each bit.

Title: Address mapping in a synchronous memory controller
Inventor: EADE PHILIP
IPC: G06F9/445
Filed: 2001-12-14
Abstract: A synchronous memory controller is able to convert an incoming physical address request relating to a given process, the request being sent from a digital component to a memory device via the controller. The same address that was used during the development of the software for that process is used by the component at run time because the controller is capable of mapping the incoming physical address request to the physical address required by the memory device for it to return the correct data for the process. Preferably the development of the process used a synchronous flash memory and the controller is able to map the associated physical address to an address in a synchronous ROM enabling either memory device to be used for the process at run time.
